Superior 55 PlusThis is a warmer version of the Superior model. The entrance door is filled with injected PUR polyurethane foam, which provides much higher thermal insulation parameters than foamed polystyrene. The wing structure is based on a stile made of high-quality, waterproof deciduous plywood. It ensures mechanical stability of the door wing in changing weather conditions. The outer door wing is equipped with two locks with three bolts and three anti-theft bolts. The energy-saving door frame prevents the formation of thermal bridges thanks to a special, two-part structure separated by a plastic insert - it is equipped with the same thermal threshold structure. The external models are equipped with three 3D hinges with a diameter of 15 mm, which makes adjustment easier. As in the case of the Superior package, you can order entrance doors of a certain height – doors are produced according to the size, without cutting the wing and frame.
